Stephen Colbert on Mitt Romney: Possible Serial Killer!

Stephen Colbert does not want to disturb you, but the leading candidate for the Republication Presidential nomination might be a serial killer.

The Comedy Central host, who is actually running in the upcoming South Carolina Primary, makes this startling accusation in a new ad from his Super PAC, one in which narrator John Lithgow follows Mitt Romney's own line of reasoning to its logical conclusion.

If corporations are people, as Romney famously said at a campaign event last year, and if Romney gutted a number of businesses during his days in the private sector, well... what other conclusion can be draw?

On ABC’s This Week today, Colbert was asked by George Stephanopoulos whether he truly believes Romney is a serial killer and replied: “That’s a question he has to answer."

Watch the commercial below and decide: Does it cross a line? Or is it a perfect form of satire?
